  Hi!

  Try this:

   fd.onsubmit(function(){
  	if ((fd.field('Name').value() || fd.field('Mailing').value()) && fd.field('Attachments').control()._el().find('#idAttachmentsTable tr').length == 0) {
  		alert('Attachments is a required field!');
  		return false;
  	}
  	return true;
  }) 

   

  However, I don't know what Name and Mailing fields' types are, take a look here at the various field types and corresponding ways of getting their values: http://formsdesigner.blogspot.com/2013/04/getting-and-setting-sharepoint-form.html

  Thanks that works. But iwas wondering why did nested if didn't work as i am trying to use it in different scenario where based on which field is empty different alerts would pop up for user.

   

  Thanks,

  Probably because you have things like this there

  fd.field('Mailing').value() != " "
  

  Whereas you probably mean

  fd.field('Mailing').value() != ""

  As well validations always returns false when i use your method for 3 fields. for example name,address and phone. If any of the field has value attachment can't be blank.

  Show us the code and tell us how you expect it to work.

   

  Regarding the code you posted initially what you are saying with it is:

  if name is not one empty space and there are no Attachments

  and mailing is not one empty space and there are no Attachments

  in that case alert and return false

  otherwise return true

   

  I presume that's not what you want. If you want to display different alert messages based on different fields being empty or not, you should do:

  fd.onsubmit(function(){
  	if (fd.field('Name').value() && fd.field('Attachments').control()._el().find('#idAttachmentsTable tr').length == 0) {
  		alert('alert 1');
  		return false;
  	}
  	if (fd.field('Mailing').value() && fd.field('Attachments').control()._el().find('#idAttachmentsTable tr').length == 0){
  		alert('alert 2');
  		return false;
  	}
  	return true;
  })
